It's really easy to find websites that will show you how to code a form and all its little inputs using HTML. The only thing is what actually happens when the user clicks "Submit." My site is www.buildmethebest.com/intel_customdesktop.php
I have a form all coded (right now there isn't a submit button, but that's not hard to do). The form is for a custom computer. I have radio buttons and checkboxes. I need the form to Submit the data and go to another page and display the information the user has selected from the form and then another textarea for them to optionally add any notes to the order. This page is to clearly display everything the user has selected and for them to confirm it. If they wish, I would like for them to be able to confirm it or go back and make changes if necessary. I then want them to click another button from the confirmation page and have the order stored in their "Shopping Cart" where they then can browse the rest of the site. Then when they are ready to "Checkout", ask the user for some shipping info, billing info etc. and then submit the data to a mySQL database. I know how to do the checkout page and submit to mySQL databases.
My question is how to store this information temporarily and display it later (like on the confirmation page). Also if it is possible, to allow the user to make changes to the order once it is in their "cart" after they have confirmed it and added it to their cart.
So, again, if this is confusing:
FILL OUT FORM -> SUBMIT -> DISPLAY DATA -> CONFIRM/ADD TO CART -> HAVE IT DISPLAYED AS IN THEIR SHOPPING CART -> CHECKOUT
I know this is alot to ask but I don't think it's anything out of the ordinary for an ecommerce site. Reason I'm doing this myself instead of like ZenCart is because of the custom order form.
I appreciate any help! Thank you!
